what will the world here next from lance armstrong? -- hear next? a military operation at an algerian gas plant appears to be ongoing, three days after al qaeda-flynt fighters took hundreds of workers hostage. although more than six other people are reported to have been released, 30 foreign workers remain unaccounted for. algerian state media says 12 hostages have died. >> these and the people we were able to escape what may have been a terrifying experience for them, and relieved, they most certainly are. algerian television took these pictures, and it shows men, with praise for the algerian army, which took on the hostage crisis. >> the algerian army. >> i think they did a fantastic job. i am very impressed. >> my thoughts are with colleagues. >> still, the most reliable estimates are that dozens of hostages remain missing, unaccounted for, and a second operation has been undertaken by algerian forces to try to find an end. hopefully, it will be better than the first one, which ended in about 30 workers killed by troops, who apparently bombed it
